# Log Construction - Implementation

## Block construction specification

In a block construction variant, as for example in an HRB file, all information for covering the walls and for connecting the bars is contained. A block construction variant thus includes all settings for various areas (e.g., wall composition, window opening, ...).\
A name is assigned for each block construction variant.

## Block construction variant - wall composition

The list displays all settings for the composition of walls. The browser button navigates to the dialog box for creating and modifying wall compositions.

The settings in the dialog box for wall compositions are saved under their own name and these settings are then available again in the definition of the block construction variant.

**Block plank identification number**: Here the identification number of the components is entered for the position in which the components are to be generated.\
The identification number can also be selected in the field via the 'quick selection'.\
Using the browser button, you can jump to the master data database dialog box. Only components of the component types bar, profile bar and plate are displayed here. However, the identification number must necessarily be associated with a profile description.

**Slope**: Because in block construction the components overlap and the identification number determines the full component height, it must be specified here what cover width the selected block plank has.

**Position**: Here the position in which the components are to be generated is specified.

**Depth position**: With this drop list the position of the block plank within the position is determined.

**Threshold identification number**: Here the identification number for the threshold is entered. The same conditions apply as for the identification number of the block plank.

**Slope**: Entry of the cover width of the threshold, as for the regular planks.

**Position**: Here the position in which the threshold is to be generated is specified.

**Depth position**: With this drop list the position of the threshold within the position is determined.
